An airway assist device (AAD) is provided. The device includes an upper AAD component and a lower AAD component. The upper AAD component includes and upper tooth guide connected to an upper plate having a pair of depending legs. The upper AAD component further includes an upper force receiving plate. The AAD also includes a lower AAD component. The lower AAD component includes a lower tooth guide connected to a lower plate. The lower AAD component further includes a lower force receiving plate. The upper and lower AAD components are connected in a way that allows relative longitudinal movement between the two components between a neutral position and a plurality of extended positions. A ratchet mechanism inhibits movement of the lower plate from any extended position toward the neutral position. The ratchet mechanism may be manually disengaged to allow the lower AAD component to return to the neutral position. An oxygen delivery housing may be connected to the upper plate to distribute oxygen.
1. An airway assist device comprising: a first airway assist component including an upper plate and an upper tooth guide connected to the upper plate;a second airway assist component including a lower plate and a lower tooth guide connected to the lower plate;the first airway assist component connec
1. An airway assist device comprising: a first airway assist component including an upper plate and an upper tooth guide connected to the upper plate;a second airway assist component including a lower plate and a lower tooth guide connected to the lower plate;the first airway assist component connected with the second airway assist component to allow relative longitudinal movement between the first and second airway assist components between a neutral position and at least one extended position to thereby allow for anterior mandibular distraction;a ratchet mechanism acting between the first and second airway assist, the ratchet mechanism allowing for movement of the second airway assist component from the neutral position to an extended position and inhibiting movement of the second airway assist component from an extended position toward the neutral position; andan oxygen delivery housing connected to said upper plate. 2. An airway assist device as set forth in claim 1 wherein said oxygen delivery housing comprises an enclosure wall connected to said upper plate to form a space between the enclosure wall and the upper plate. 3. An airway assist device as set forth in claim 2 wherein said oxygen delivery housing further comprises a tubing connecting portion defining a fluid passageway. 4. An airway assist device as set forth in claim 3 wherein the upper plate includes at least one opening in fluid communication with space between the enclosure wall and the upper plate. 5. An airway assist device as set forth in claim 4 wherein the tubing is connected to an oxygen source. 6. An airway assist device as set forth in claim 1 wherein said oxygen delivery housing comprises an enclosure wall and a septum connected to said upper plate to form a plurality of spaces between the enclosure wall and the upper plate. 7. An airway assist device as set forth in claim 6 wherein said oxygen delivery housing further comprises at least one tubing connecting portion defining a fluid passageway with each of the plurality of spaces. 8. An airway assist device as set forth in claim 7 wherein the upper plate includes at least one opening in fluid communication with each of the plurality of spaces between the enclosure wall and the upper plate. 9. An airway assist device as set forth in claim 8 wherein at least one tubing is connected to an oxygen source and at least one tubing is connected to a carbon dioxide monitoring system. 10. An airway assist device as set forth in claim 1 wherein the ratchet mechanism comprises a pawl on one of the upper plate or the lower plate and a plurality of teeth on the other of the upper plate or the lower plate. 11. A method of maintaining airway patency comprising: positioning an upper tooth guide of a first airway assist component relative to a patient and positioning a lower tooth guide of a second airway assist component relative to a patient, the second airway assist component being in a neutral position;applying a force to the second airway assist component in a direction away from the patient to move the second airway assist component relative to the first airway assist component from the neutral position to an extended position to thereby distract the patient mandible; andmaintaining the second airway assist component in an extended position by a ratchet mechanism on the first airway assist component and the second airway assist component. 12. The method of maintaining airway patency as set forth in claim 11 further comprising releasing the ratchet mechanism to thereby allow the second airway assist component to be moved toward the neutral position. 13. The method of maintaining airway patency as set forth in claim 11 further comprising providing an oxygen delivery housing having an enclosure wall on said upper plate and creating a space between the enclosure wall and the upper plate and delivering oxygen to the space. 14. A method of maintaining an airway as set forth in claim 11 further comprising monitoring the patient's end-tidal carbon dioxide wave form and respiratory rate.
